 Posted: Tue Dec 08, 2009 8:42 pm Post subject: front panel audio/usb cable error workaround |
 |
|
I was getting front usb cable error and front audio cable error on post from a Vostro 220 motherboard that I'm not using in a Dell case. I couldn't find any information on how to fix it, and this seemed like a relevant place to post...
Anyway, it's pretty easy, you just need 3 jumpers.
The audio is the Azalea standard connector. http://www.intel.com/support/motherboards/desktop/sb/CS-015851.htm Put the jumper on pins 2 and 4 to make it think that a front panel audio box is connected. This was good enough for me in Linux, but it doesn't do anything with the jack sense pins, so windows may mute the speaker output. In that case you'll have to come up with some way to connect pins 6, 7, and 10 together.
The USB ports seem mostly standard also (yeh, how refreshing). However, using a regular usb panel connector may not work. The shield ground pin (the one next to the missing one) needs to be connected to ground somewhere off the board. For my 220 board, this only needed to happen to USB1 and USB2, you can use USB3 however you want. So I just slapped a jumper grounding the shield pin on each to the adjacent USB ground pin as I'm not using them. If you need that many ports, you'll have to wrap a wire around the pins or something so you can still use them. |

Additional Info:
I recently purchased a CM Storm Scout case, and the audio pins on the Vostro 220MT motherboard uses the "HD AUDIO" connector from the case, not the AC'97 (for those who are confronting this issue).
My Questions/Issue:
I'm receiving a front USB cable error from American Megatrends after the BIOS screen. I've been hitting F1 to continue with boot for the past month, and now I'm getting a bit sick of it.
I compared the plugs from the CM Storm Scout with those from the stock Dell case, and a noticed that the Dell plugs had a wire (presumably a ground) that connects the top right pin (the pin above the missing pin) to the pin immediately left of it.
In the CM Storm Scout, this wire is not present, and I assume this is why I'm receiving this error.
So how can I overcome this? Do I just get some wire, and wrap the exposed ends around those two pins, and plug in the USB plug from the front panel on top of it? I would essentially like EzDi's secondary explanation broken down to simple steps that I could follow
(Sorry for reviving this old thread, but it applies to my situation) |

Well, I don't know which way is right and which is left, but you are probably right.
All the pins are in pairs except one. That pin, without one next to it is the shield pin.
The pin next to that one is ground, as is its pair.
http://www.allpinouts.org/index.php/USB_-_Universal_Serial_Bus
key means does not exist, and pin 10 is actually used to connect the shield.
Take a small wire and wrap it around the shield pin and a ground pin and you're good.
Alternately, you can just use jumpers on ports 1 and 2 and not use them for actual USB. If you need a front port, just use #3. Then you won't have to worry about accidentally shorting the port with your wire. |
